I don't know why I just thought of this, but here it goes. I took my private checkride, over a year ago, in a 172. The check pilot asked me what kind of flaps the 172 had. I told him Fowler, since they slid back on a track when set to one notch, and then lowered when more flaps were commanded.
He said I was wrong and they were slotted. We had a good discussion about it, and I said they shoudl be Fowlers since they slid back more than down on the first setting and increased wing area. But the POH said slotted, so that's what he wanted. (It didn't affect me, though, I sill passed. haha)
SO, what kind of flaps does a Cessna 172 have? Slotted or Fowler?
